GAS-LIGHT.

Specification of Letters Patent.

Patented Feb. 5, 1907.

Application filed March 23,1906 Serial No. 807,752.

To all whom it may concern:

Be it known that I, HARRY W. MANNING, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain. new and useful Improvements in Gas-Lights; and I do hereby declare the following to be a full, clear, and exact description oi the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to gaslights, and especially to that class of gas-lights employing incandescent mantle depending from the gas supplying pipe.

The object of the invention is to provide a gas-light employing a depending mantle and embodying means whereby the said mantle may be surrounded by a globe opened only at the upper side.

A further object of the invention is to provide means in association with a gas-light employing a depending mantle and a surrounding globe for introducingnir to the said globe in such manner that the currents of air move along the entire surface of and to maintain the said globe in a cooled condition.

Afurther object of the invention is to provide a gas-light embodying means for employing a plurality or cluster ct" depending mantles surrounded by a globe opened only at its upper side and arranged for the admission of air upon the inner surface of the said globe -tor cooling the same.

With these and other objects in view the invention comprises certain novel construetions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the drawings, Figure 1 re n'esents diametric sectional view of the improved gaslight. Fig. 2 is a view in side elevation ol 2 he f sleeve and deflector-plate for guiding the aircurrents. Fig. 3 is a view in side elevation of the cluster-light arranged in accordance 1 with this invention and with a portion of the globe and sleeve broken away to exhibit the cluster of mantles.

Like characters of reference indicate eorre. sponding parts throughout the several views.

In its preferred embodiment the gas-light forming the subject-matter of this applicaj tion comprises a mantle of substantially 1 the usual form and pattern used as a depcnding mantle and secured upon the gooseneck 11 in any approved manner, as by the collar l the sleeve.

12, provided with a bayonet-joint 13, engaging a bulb or similar device, (shown at 1 1,) which said bulb is connected with the tubular portion 15, adjustably held upon the gooseneck 1 1, as by a thumb-screw 16.

About the tube 15 is secured a sleeve 17 in any approved manner, as by means of the spider 18, the said sleeve being belled, as at 19, at the lower end and with its upper end widely flanged and curved, as at 20, with the annular concaved portion of the said flange opened downwardly. About the sleeve 17 is secured'a hoop 21 in any approved manner, as by the spider 22, the said hoop being proportioned to receive the upper opened side of the globe 22 and provided with any approved means, as the thumb-screw 2 1, for engaging the common and usual groove 24, formed in the said globe. The goosencck 11 is secured to the gas-conducting pipe, as 25, by means of the usual air admitting and regulating device (shown in elevation at 26) and carrying an upwardly-extending shank 17, upon which the gooseneck is removably placed.

For using a cluster of mantles, as at 28, the sleeve 29 is tapered so that the lower belled end 30 is larger in proportion than the belled end 19. (Shown in Fig. 1.) The sleeve 29 is provided with a curved flange similar to the flange 20 and similarly located relative to the hoop 32, within which is sccured the globe 33 in the manner described for the globe 23, and the device is adjustable by means of the tube 34 and thumb-screw 35 upon the goosencck 11.

It will be noted that in either of the forms shown at Fig. 1 or Fig. 3 the globe is secured j with its upper open end immediately below the curved .[langes 20 and 31, which extends outwardly beyond the stud open end 01" the globe and whereby the air-current entering the said globe is given a curved movement to throw the said -current against the curved inner side of the globe, which said inner side 1 the said air-currents 'lollow until subjected to the upward current between the mantle and It is obvious that the air-currents following the said flange with the iurved movement, as indicated by the ar rows, will substantially .l'ollow the curvature of the globe, so that the said globe is at all times maintained in a cooled condition and not liable to breakage by external air-cur rent. v

Particular stress is laid upon the formation of the curved flange 20, extending outwardly beyond the globesupporting hoop 21 and being nrved, as shown, to produce the necessary curvature of air-currents to throw the said air-,nrrents against the sizrface of the interior of the globe and to the lower belied end of the sleeve, whereby practically all of the heat generated at the mantle is retained Within the sleeve, causing the air-enrrent-t-o move upwardly throgh the interior of the said sleeve and not externally thereof, as world be the case if the said lower end were not helled.

What I claim is 1. In a light of the class described, a sleeve belled at its lower end and provided with an olittnrned curved flange at its upper end, a gas-rnantle disposed partially within the lower helled end of the said sleeve, and a globe surrounding the said sleeve and mantle and open at its upper side, and with the periphery of its open side disposed beneath the center of curvature of the flange.

2. In a gas-light or" the character described, a sleeve provided with a belled lower end,

and with an onttrirned flange at its upper end, curved to form a downwardly-opening annular concavity, a gas-mantle disposed position and having a belled lower end, and

with an onttnrned llange at its upper end, curved to form a downwardly-open anntlar concavity, a pipe extending axially within the said sleeve and provided with a mantle at its lower end disposed partially within the helled end of the said sleeve, and a globe S121- ror nding the said mantle and sleeve and open at its ripper side, and with the periphery of its open side disposed substantially at the center of ctrvattre of the said flange.

In testimony whereof 1 till my signature in presence of two witnesses.
